These guys are the best! They get my orders processed and to me fast and of all the brass i have purchased from them i have yet to receive one piece that was not usable. For top quality reloading brass, Diamond K is the place to shop.....

Completely awesome place to do business with. Made and order of 308 Nosler 168 grain projectiles and 100 cases, shipping was one of the fastest I've seen......even here to Honolulu! and the condition of the cases was outstanding. I look forward in doing business with Diamond K Brass again in the near future.

I ordered 1000 .45 ACP LARGE pistol primer brass a while back and just got around to loading some of it today. I encountered a Blazer SMALL pistol primer shell which fortunately only jammed up my machine. That is the best thing out of many bad things that can happen when one tries to shove a large pistol primer into a small pocket.
I went through the rest of the 1000 cases and found 5 more SPP cases. Be sure and double check your cases if you order any cases that are available with small and large primer pockets. Side note: WHO THOUGHT THAT WAS A GOOD IDEA? Other than that issue, I am a happy customer.

Short, sweet and to the point. "PERFECT"

Placed order last Friday (12/30/16) arrived today (1/2/17) Priority USPS (and today is supposed to be the observed Federal Holiday). Now THAT is Outstanding Service!

Diamond K is as good as it gets. Recently ordered some 30-06 military cases, and received them in four days. That's as fast as you can go from Arizona to New York using standard shipping rates. The brass is excellent, and better than hoped for. Glad I did business with Diamond K.

I ordered 2,500 used brass in .357 Sig. It arrived two days later in excellent shape. Good quality brass, clean, no dings or dents. I will be ordering again.

Bought some AK brass during the COVID-19 shortage. Fair prices, shipped almost instantly. Back now that they have bullets in stock! It doesn't get better than DiamondKBrass!

I've ordered 41 magnum brass I have also ordered 4440 brass all of it has been clean very satisfied with my order will order from them again

Ordered 1000 pcs of 45acp brass and am very pleased will do business with Diamond K again received my order 3 business days after it was placed and brass looks good.
